These books were published by a group
called The National Home Library Foundation, Washington, D.C.

They are all slightly different sizes,
but they're generally the size of mass market paperbacks. All three of
these were printed in 1940. My copy of Free Enterprise
appears to have been signed by the author, Wendell Willkie, who ran for
president that year against Franklin D. Roosevelt.

The books are all very conservative,
very pro-capitalism and they urge Christian-based themes in democracy.
While FDR is not mentioned in the books, they all stress that the nation
is "in crisis."
